<p>Yeah, i put decomposers also..</p>
<p>Damnit... I was debating between the two, but I then chose parisitism. :( Small chance that it could be right though! ;)</p>
<p>"cause organisms cant know where the decomposer are"</p>
<p>what does if the organisms know matter.</p>
<p>as i read it online, decomposers provide nutrients to allow for more primary production, which would allow all other trophic levels to expand. also, they eliminate bodies and possibly toxic waste..</p>
<p>HOWEVER if the question says "LEAST direct" (which i dont remember but its entirely possible) then im pretty sure decomposers would be the answer...f**k.</p>
<p>o and the most likely time for conception is after release of the egg? and all of this</p>
<p>"making sure --- the one on E with the branch being 4 feet and then it growing 2 feet was ... 6 feet right? the following question was root and shoot meristems?</p>
<p>the very last core question (for me) was about the experiment with temperature effects on the reaction and enzymes and it asked between 25-35 degrees. was it I and II only?</p>
<p>the one with which wasnt a membrane bound organelle or w/e was chromosome. im almost positive.</p>
<p>on the part witht he bird being introduced int he 1900s and the map or w/e, wasnt the first questions (with keeping the birds biological safety or population size) was study the ecological habits or something (E)?"</p>
<p>cause the other factors would have a more direct effect, like competation organisms are competing, for decomposers its in the ground and not directly related to them, but mostly to plants, and plants cant move so the effect is least!</p>
<p>yeah conception after release of egg</p>
<p>no it was 4 feet the branch does not move up, cause it grows from the top! and growth happens at the shoot meristems and stuff. </p>
<p>i don't remember effect of temperature! i believe it was only because more diffusion cause particles are moving faster so more contact with enzyme. </p>
<p>Membrane bound is not chromosome. Thats rite!</p>
<p>K and yeah i put E for the study first!</p>
<p>thanks for ur answers. im pretty sure II was true, although i dont remember it. was it something about the increase in temperature increases rate. in that interval it was true...</p>
<p>Yes increase rate increase temperature! </p>
<p>What about the question about the mouse and cricket and the BMR!</p>
<p>i f'ed up on the karyotype >:( i would have read carefully, but for some reason any SAT test ends up ****ing me off xD</p>
<p>BMR basically stated the mouse is endothermic and has to change BMR with temp. change. the cricket did not really.</p>
<p>What was the answer to (I think it might've been in the M section) the lab question where the egg was radioactivat(ed) with a protein and then the activity of the protein increased right after fertilization? Like for the last question, "what would be a good control for the experiment?" was the answer something like divide the sperm in two or something (i think the choice E)??
And then what was a good explanation for the activity increaseing after fertilization?</p>
<p>For the radioactive fertilization one, I think that I put the answer about dividing fertilized sperm from unfertilized sperm. I can't remember what the other question about that lab was, though.</p>
<p>oh kay
and then for the one where it said when does fertilization occur, does anybody remember the answer choice?</p>
<p>it occurs after ovulation.
For the exp. It is sep. the sperm..b/c i took a PR test the day before and t almost had the exact same experiment.</p>
<p>the one with the mouse, it was the 2nd endothermic one (E) for me. i forgot wat it said</p>
<p>sweet! got that right.
aa6590, i didnt guess on it so i skipped it but it was either D or E, the endotherm ones.
the other radioactivity question was something like 'why did the activity increase after the egg was fertilzed' and i put because proteins needed to be created in the embryo.</p>
<p>also for the bird lab set of questions, has it been decided that:
1935-45 when the species spread over US
that we should study them first
that introducing new species as cmpetetiors will control the pop.
the last question had the answer of something along the lines of native species?</p>
<p>i put endothermic because mice are warm blooded</p>
<p>When do we get scores????</p>
<p>june 21</p>
<p>for the bird thing, the principal objection was that the starlings posed a threat to native species due to competition for resources. wouldn't inroducing a new species magnify this problem?</p>
<p>also, for the substrate thing, did anyone else get that it was inversely proportional?</p>
<p>i put proportional only at low levels</p>
<p>yeah me too. because at low levels it seemed proportional but at high levels it was unrelated.</p>
<p>hey didn't someone post all the answers or something and then have them taken down?
do we still have that?</p>
